Turku, Finland – August 26, 2025 — Gasum, a leading Nordic energy company specializing in low-emission fuels, and Viking Line, a Finnish shipping company renowned for its sustainable passenger and cargo operations in the Baltic Sea, have taken a decisive step toward maritime decarbonization.
In a landmark move aligned with the European Union’s FuelEU Maritime regulation, Viking Line has begun operating its flagship vessels, Viking Grace and Viking Glory, on bio-LNG supplied by Gasum. The initiative supports the compliance generation needs of Gasum’s FuelEU Maritime (FEUM) pooling service, a platform designed to help shipowners meet and exceed EU emissions targets by pooling low-emission fuel use across fleets.
Powering Progress with Predictability
Viking Glory and Viking Grace operate on the high-frequency passenger and ro-ro cargo route between Turku, Finland, and Stockholm, Sweden—a route traversed daily across the Baltic Sea. This consistency provides reliable and predictable emission reduction data—a vital factor in optimizing the FEUM pool’s compliance mechanism.
“Demand for FEUM pooling is becoming so high that it would not be possible for Gasum to generate the needed compliance using just its own bunkering vessels anymore,” explains Jacob Granqvist, Vice President, Maritime at Gasum. “That’s why partnerships like this one with Viking Line are essential to scaling and stabilizing our service. We’re thrilled to expand our long-standing collaboration.”
Leading the Charge to Fossil-Free Maritime
Viking Line, a long-time champion of greener shipping, views the bio-LNG transition as a natural evolution of its sustainability mission.
“We aim to be among the frontrunners as Finnish maritime shows the world how to transition to a fossil-free future,” says Jan Hanses, CEO of Viking Line. “For two years, we’ve offered our passengers and cargo clients the option to purchase biogas for their journey between Turku and Stockholm. Now, by increasing our bio-LNG use to 50%, we can significantly cut emissions across the route.”
This ramp-up in bio-LNG adoption reflects Viking Line’s long-standing investment in dual-fuel vessels and innovative clean-fuel technology—pushing the bar higher for eco-conscious ferry operators across Europe.
A Verified Pool for Real-World Impact
Gasum’s FuelEU Maritime pooling service offers a comprehensive compliance solution for shipping companies operating both conventional and dual-fuel fleets. By managing fuel supply, emission tracking, and regulatory reporting, Gasum allows operators to maximize their use of over-compliance credits, thus lowering their overall decarbonization costs.
The data integrity of the pool is safeguarded through collaboration with DNV, a globally recognized classification and verification body. DNV monitors, validates, and verifies the fuel consumption and emissions data, ensuring that all compliance reporting is robust and audit-ready for EU authorities.
The Fuel Behind the Future: Bio-LNG
Gasum fuels the pool with waste-based liquefied biomethane (bio-LNG), deployed on selected vessels equipped with dual-fuel propulsion systems. This bio-LNG is 100% renewable, achieving up to 90% lower lifecycle greenhouse gas emissions compared to traditional marine gasoil (MGO).
By leveraging bio-LNG, shipowners participating in the FEUM pool can turn their low-emission efforts into tangible compliance credits, which can be allocated to their conventional fleet under the FuelEU Maritime regulation—a groundbreaking EU policy designed to decarbonize shipping by enforcing gradual reductions in carbon intensity across maritime fuels.
FuelEU Maritime Pooling: A Decarbonization Catalyst
At the core of the FuelEU Maritime regulation lies the concept of voluntary pooling, which allows vessels with superior environmental performance—like those operated by Viking Line—to generate compliance credits for vessels with conventional fuel profiles.
Gasum’s pooling service acts as a centralized platform that aligns with the EU’s regulatory vision while also accelerating the market adoption of renewable fuels like bio-LNG.
With Viking Line now actively contributing to the FEUM pool, the service gains increased credibility, volume, and impact, enabling more shipowners to participate in emissions pooling and comply with the upcoming 2025 and 2030 FuelEU Maritime benchmarks.
Conclusion
The integration of Viking Line into Gasum’s FuelEU Maritime pool represents a defining moment for the maritime bunkering and compliance landscape in Europe. It is not only a model of strategic collaboration but also a tangible step forward in turning environmental ambition into regulatory success.
As the FEUM regulation looms on the horizon, this partnership sends a clear message: the future of shipping is renewable, cooperative, and already in motion.
